Curator Hierarchy Locking (overlapping locks)

I was able to successfully get lock on /ads/lock/0-test1 and then couldn't get a lock on /ads/lock

How can I solve this?

InterProcessMutex lock1 = new InterProcessMutex(client, "/ads/lock/0-test1");
if(lock1.acquire(30000, TimeUnit.MILLISECONDS)){
   InterProcessMutex lock2 = new InterProcessMutex(client, "/ads/lock");

   if(lock2.acquire(30000, TimeUnit.MILLISECONDS)) {  //Failing
   ...
   }
}

Update: This is the essence of what's happening in this https://github.com/Microsoft/Cluster-Partition-Rebalancer-For-Kafka/ZookeeperBackedAdoptionLogicImpl.java Locks at line 250(detailed path) and 299(Root path) are sequential. So, when another instance tries the lock a detailed path (250), the lock fails as the root path (299) is locked. The logic is valid but the root lock is never obtained

Update 2: I wrote a small program to check whether overlapping locks work and It does.

public class LockTesting {
    public static final String ROOT_LOCK = "/locks";
    public static final String CHILD_LOCK = ROOT_LOCK+"/child";
    private static CuratorFramework client;

    public static void main(String[] args) throws Exception {

        client = CuratorFrameworkFactory.newClient("127.0.0.1:2181", new ExponentialBackoffRetry(1000, 30));
        client.start();
        InterProcessMutex lock1 = new InterProcessMutex(client, CHILD_LOCK);
        if (lock1.acquire(30000, TimeUnit.MILLISECONDS)) {
            System.out.println("Child Locked");
            InterProcessMutex lock2 = new InterProcessMutex(client, ROOT_LOCK);
            if (lock2.acquire(30000, TimeUnit.MILLISECONDS)) {
                System.out.println("Root Locked");
            }
        }

    }
}
